So the rear deck 6x9's in the TSX sound decent for bass output which is basically what they are supposed to do, but I wanted some more thump and with a baby and needing a tote around a stroller I just didn't have room for my Type R, box, and amp. So instead I replaced the Pioneer 6x9's that the TSX comes with for some Infinity Kappa 692.7i's. Let me be the first to say these are AWESOME! They have a great bass output, similar to what a 10" sub or two 10's sound like! Install was relatively easy, Crutchfield.com supplied a harness adapter for the rear deck which is plug and play and i had to slightly modify the ends coming out of it for use with the crossovers that the infinity's come with. The I had to drill two extra holes in the speaker mounts to screw into the car. That is quite easy, just drill through the stock hole on the car straight through. All in all installation took about 45 minutes and the reward is great! I would reccomend this to anyone who wants more bass but doesn't want to sacrifice trunk space!

 

As much as those are fine speakers, there is no way they "have a great bass output, similar to what a 10" sub or two 10's sound like". Its just not possible with the signal going to those wires, which is clipped in frequency and all of about 12watts powerful.

Listen to someone who has a full frequency line going to an amp w/ a real sub setup before making such a claim. I'm sure its a fantastic upgrade over stock (I believe you) but I don't want anyone else to read this and think "I might as well not get a sub now..." because they will be dissapointed.

 

Just followed in your footsteps clee...infinity install happened tonight...boy do they sound great. Wasn't happy about the drilling the other two holes, but at least it was just into the speakers and not into the deck. Now I just need to update the rest sometime and really let her stretch her vocal chords...lol
